DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball stop structure for a transfer gutter for guiding a pachinko ball in a ball tank to a pachinko ball dispensing device.

[0002]

2. Description of the Related Art Conventionally, a mechanical plate made of synthetic resin is mounted on the back of a game board of a pachinko machine, and a ball tank is fixed on an upper portion of the mechanical plate. Further, a transfer gutter for guiding the pachinko balls stored in the ball tank to the pachinko ball dispensing device is provided below the ball tank, and a ball stopper member is rotatable on a horizontal axis inserted over the transfer gutter. Is provided.

[0003] The ball stopper is provided integrally with a ball stopper corresponding to the ball passage of the transfer gutter. For example, when a failure such as a ball biting occurs in the pachinko ball dispensing device and it becomes necessary to repair the ball. The ball stopping member is rotated to the ball stopping position so that the ball stopping piece protrudes into each ball passage of the transfer gutter, thereby preventing the pachinko ball from flowing down.

[0004]

By the way, a pachinko ball dispensing device used in a recent pachinko machine uses a sprocket or a pachinko ball having a concave portion formed on an outer periphery for receiving a pachinko ball flowing down a ball passage of a transfer gutter. By rotating a lead screw, whose receiving recess is formed spirally on the outer periphery, with a motor, the pachinko balls in the ball passage of the transfer gutter are discharged one by one. That is, when the ball path of the transfer gutter has, for example, two rows, the pachinko balls in each ball path are dispensed one by one while alternately moving at a predetermined pitch (for example, the radius of the pachinko ball) with the rotation of the sprocket or the lead screw. Therefore, the stop positions of the pachinko balls in the two rows of ball paths are alternately shifted left and right depending on the number of pachinko balls paid out.

[0005] However, in the conventional ball-stopping member in which the ball-stopping position is always determined by the ball-stopping member, the ball-stopper hits the pachinko ball in the ball passage depending on the stop position of the pachinko ball. The ball cannot be stopped. For this reason,
The realization of a ball stopping structure that can deal with the electric pachinko ball dispensing device as described above is an urgently required issue.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a pachinko machine capable of reliably stopping a pachinko ball in a ball passage of a transfer gutter with a simple structure. An object of the present invention is to provide a ball stop structure for a transfer gutter.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a pachinko ball of a ball tank which is rotatable between a ball stop position and a ball stop release position on a transfer gutter for guiding the ball to a pachinko ball dispensing device. In a pachinko machine that supports a ball stopping member, a shaft through hole of the ball stopping member is formed in a long hole shape, and the ball stopping member is provided so as to be movable in a flowing direction of the pachinko ball. It is.

[0008] The transfer gutter is constituted by two members, a tank rail portion for guiding the pachinko balls of the ball tank in alignment and a curve rail portion for guiding the pachinko ball dispensing device while reducing the ball pressure of the tank rail portions. It is preferable to provide a ball retaining member on the curve rail portion.

It is preferable that the ball stopping member is provided with a horizontal axis on a curve rail portion or a mechanism plate, and is rotatably fixed to the horizontal axis.

It is preferable that an engaging projection is provided on the ball stopping member, and an engaging concave portion is provided on the upper surface of the curved rail portion so that the engaging protrusion is engaged at a ball stopping releasing position of the ball stopping member.

In the pachinko machine having the above-described structure, the transfer gutter ball stopping structure of the pachinko machine can be freely moved in the downflow direction of the pachinko ball within the range of the axial through hole in which the ball stopping member has a long hole shape. Therefore, for example, even if the stop positions of the pachinko balls in the two rows of ball passages alternate alternately left and right by a predetermined pitch, the ball stoppers are moved into the ball passages by moving the ball stopper members in accordance with the stop positions of the pachinko balls. It becomes possible to stop the ball.
